will enable others skilled inthe art to which it appertains to make and use the same.

This invention relates to attachments to sewing machines, and has for its primary object to provide a simple and efficient device attachable to the presser foot of a sewing machine and embodying an adjustable guide arm designed to facilitate stitching along a line parallel and in predeterminedspaced relation to the edge of the fabric or other material being sewed.

Another object is the provision of a sewing machine attachment of this character embodying means whereby the guide arm may be moved to inoperative position when not in use.

lVith these and other objects in View, the invention consists in the novel construction, combination and arrangement of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a. perspective view of the attachment,

Fig. 2 represents a side elevation thereof, partly in section,

Fig. 3 represents a front elevation of the presser foot and attachment applied thereto,

Fig. 4 represents a rear elevation of the presser foot, and

Fig. 5 represents a transverse sectional view on the line 5-5 of Fig. 2.

Referring to the drawing in detail, wherein similar reference numerals designate cor responding parts throughout the several views, the numeral 6 indicates generally a presser foot designed for use in connection with standard types of sewing machines, and it includes a relatively stationary part 7 and an adjustable supplemental part 8 slidably engaged in a recess formed'in the bottom or heel of the foot 9 carried by the relatively stationary part 7 and frictionally secured in adjusted position with relation to the stationary part 7 by a spring 10, having an angular end engaged in a slot 11 formed in "the upwardly directed reap 12 of the supplementalpart 8. j i 1 v U A leaf spring 13 is secured'centrallyadj acent the upper end of the stationary part '7 of the presser foot by ascrew 1 1 andis preventedffrom swinging upon ,the screw 14 by. a pin" 15 carried by the stationary part 7 The lower extremity of the spring 13 is normallyretained in engagementw'ith the front face of the vertical member of the stationary part 7 of the presser foot by the rearwardly and downwardly directed upper end 16 of the spring, which ism gaged in a recess 17 formed in the'stationary part 7. i

A holder plate 18 is slidably engaged with the front face of the leaf spring 13 andv is formed with a plurality of rearwardly directed fingers 19, several of which engage the vertical edges of the vertical member of the stationary part 7, While others of the fingers 19 are bent about the longitudinal edges of the spring 13.

A relatively long and horizontally disposed plate 20 is slidably mounted between the vertical member of the stationary part 7 and the lower extremity of the leaf spring 13 and is confined between several of the fingers 19 carried by the holder plate 18. The front face of the plate 20 is marked to represent any desired scale to facilitate adjustment thereof. A forwardly directed guide or gage arm 21 is rigidly secured to the horizontally disposed plate 20 and is adapted to cooperate with the edge of the material being sewed during the use of the attachment. I

By moving the plate 20 longitudinally between the lower extremity of the spring 13 and the stationary part 7 of the presser foot thev desired adjustment of the gage arm 21 with relation to the foot 9 may be obtained while the plate 20 and arm 21 may be adjusted vertically or, if desired, moved to inoperative position by sliding the holder plate 18 vertically upon the spring 13 and stationary part 7 of the presser foot. The plates 18 and 20 are secured in adjusted vertical position by a spring securing member 22, pivotally secured at its lower end to a forwardly directed pin 23 carried by the plate 18 and having an angular-1y directed lug 24 at the upper end thereof adapted to be engaged in any one of a plurality of vertically spaced apertures 25 formed ad acent the upper end of the spring 13, A laterally projecting handle 26 is formed upon the upper extremity of the securing member 22 to facilitate adjustment of the holder plate 18 and gage arm 21.

hat is claimed is:

1. In combination, a sewing machine presser foot, a leaf spring secured to said presser foot and normally engaged with the front face of the latter, a horizontally disposed plate movable longitudinally between said spring and said presser foot, an angularl directed 'a 'e arm carried b said plate, a holder plate slidably engaged with said leaf spring, and a plurality of fingers carried by said holder plate slidably recei ing the first-mentioned plate for securing the holder plate in adjusted position upon said spring.

2. In combination, a sewing machine presser foot, a leaf spring secured to the presser foot and normally engaged with the front face of the latter, a horizontally disposed plate movable longitudinally between said spring and said presser foot, an angularly directed gage arm carried by said plate, a holder plate slidably engaged with said leaf spring, a plurality of fingers carried by said holder plate slidably securing the first named plate, and means connected to the holder plate and to the spring for holding said plate in a vertical adjusted position.

3. In combination, a sewing machine presser foot, a leaf spring secured to said presser foot and normally engaged with the front face of the latter, a horizontally disposed plate movable longitudinally between said spring and said presser foot, an angularly directed gage arm carried by said plate, a holder plate slidably engaged with said leaf spring, a plurality of fingers carried by said holder plate slidably receiving the first mentioned plate for securing the holder plate in adjusted position upon said spring, and a resilient securing member connected to the holder plate and to the spring for holding said plate in a vertical adjusted position.

In testimony whereof I affix my signature in presence of two witnesses.
